Pair of antique chairs that have been recovered at least twice. Haven't found anything exactly like them via google. Maybe teak? Original seat cover appears to be a wheat spray patterned, rose colored silk (?).
Not sure if the mark on bottom of seat is for the actual chairs, or just a replacement seat cushion.
Looking for info on when they may have been made, and if they have value. They would clean up nicely with new pad.
Armchairs
Your 19th century Late Classical armchairs look to be walnut (it's hard to tell from photos). They'd bring about $300 at auction. Very nice!
